Title: Waveform reproducing circuit for transmission signal
Inventor: KATSUMATA NORIAKI
IPC: H04B3/06
Filed: 1986-05-23
Abstract: PURPOSE:To obtain a reproduced output resulted from sure frequency correction by providing a gain control means of the transmission signal level in a circuit which corrects the frequency of the transmission signal by F<1/2> AGC. CONSTITUTION:The transmission signal has the frequency characteristic and the output signal level fixed by the loop passing an AGC 3, an LPF 4, and a peak holding circuit (PH) 5 and is given to a frequency correcting circuit 1. The output of frequency correction in the circuit 1 is inputted to a PH 2 through a BPF 6. By this constitution, the gain control means in the preceding stage controls the gain by the low frequency component level of the transmission signal. The transmission signal which has the low frequency component controlled to a required level by the gain control means in the preceding stage is inputted to the frequency correcting means in the succeeding stage, and this frequency correcting means controls the gain of the high frequency component of this input to a required level to correct the frequency. Thus, the improperness of frequency correction based on the level of the transmission signal is eliminated by the gain control means to obtain a sure waveform reproduced output resulted from sure frequency correction.

Title: Operation control device of brushless motor
Inventor: OGAWARA HIDEJI
IPC: H02P6/182
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To prevent out-of-step on migration, by verifying the pattern of a rotor position detection signal when the final commutation signal pattern of a synchronous operation mode is outputted before migrating from the synchronous mode to a rotor position detection operation mode, and by sending an appropriate commutation signal to a rotor position. SOLUTION: In a rotor position detection operation mode on normal operation, a brushless motor 3 is operated by a commutation signal being generated via a rotor position detection means 6. On activation, the commutation signal is given with a low frequency as a synchronous operation mode and the motor 3 is forcibly rotated. On migration from the synchronous operation mode to the rotor position detection operation mode, a final commutation signal pattern is outputted, the synchronous operation mode is ended, and the rotor position detection signal is read. Then, a specific commutation signal that should be outputted by the pattern of the rotor position detection signal is determined by a position signal pattern judgment means 10, thus migrating to the operation mode relatively normally and starting a device stably and quickly.

Title: Character recognizing device and computer-readable recording medium
Inventor: TANAKA HIDEAKI
IPC: G06K9/62
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To realize a reject valid even to a missing character by setting an established circle for turning a miss path into 0. SOLUTION: The maximum value of the similarity of a category to be recognized for a character in a recognition dictionary 8 is stored in a similarity maximum value table 10. The average and standard deviation of the rate of the width and height among all the categories to be recognized are stored in a shape table 11. A reject controlling part 12 obtains the maximum value(established value) of the similarity maximum values in the second - (m)th ranks from the similarity maximum value table 10, and considers the recognized result that the similarity of a candidate to be recognized in the first rank is less than the established value as similarity reject. Thus, the miss path can be turned into zero.  Also, the reject controlling part 12 obtains the average and standard deviation of the rate of the width and height of a character under consideration with that of an objective character, calculates the shape value of the character under consideration, and calculates cumulative values related with all the objective characters. Then, the character under consideration whose cumulative value is larger than a threshold value is considered as the object of shape reject.

Abstract: PURPOSE:To construct a building subsurface structure safely and economically by reducing the variation of the ground water levels of-up-and streams when the structure is constructed. CONSTITUTION:In the constructing method of a building subsurface structure 2 through a muddy-water excavation method, cooling pipes (coolillg feed pipes 11a, 11b) are inserted while a reinforcing material is built, and freely freezing- thawing water-permeable fillers are charged to desired limited sections in an excavated ditch, thus constructing water permeable layers 9a, 9b.

Filed: 1995-04-21
Abstract: PURPOSE:To achieve higher reliability by arranging a plurality of address signal parts at an address area section to perform a recording or a reproduction for a desired sector by any one address output with no error detected. CONSTITUTION:Track addresses of the same contents are recorded twice at a time interval T at address area parts of respective tracks. When a track address reproduction output (b) decoded to an NRZ signal with a decoding circuit 10, for example, comprises a track address of 16 bit, a deformation hamming code of 6 bit, a cyclic code of 16 bit and the like. When no error is detected with a cyclic code checking circuit 12, a track address (m) is outputted immediately. When errors in the cyclic code are detected, an error detection/correction circuit 16 executes the correction of errors. At this point, the same error detecting/correcting operation is repeated for a second track address reproduction output (b) to collate the results. The time interval T is set longer than the time necessary for the error detecting/correcting operation.

Title: Parts orderly feeding method in spiral type vibrating parts feeder
Inventor: TAKAHASHI TERUO
IPC: B65G47/14
Filed: 1985-06-04
Abstract: PURPOSE:To improve efficiency in the orderly feed of parts ever so better, by feeding parts orderly with a relative vibration to a parts receiving vessel of an orderly feed track, or accelerating the orderly feed action otherwise. CONSTITUTION:There is a step difference between a track 10 of a pole 2 and a passage 11a of an orderly feed track 11 so that parts (m) receive such turning force that changes them from a lying attitude to a rising one when transferring to the orderly feed track 11. Since the orderly feed track 11 secondarily vibrates in vertical directions, it also receives a torsional vibration of the pole 2 but with this track 11, a transfer rate of the parts (m) becomes smaller than that of the track 10 of the pole 2. Therefore, these parts (m) come into a state of being pooled hereat, whereby they are interconnected with the rising attitude and transferred. In this connection, the secondary vibration in vertical directions serves as stably holding this rising attitude. In addition, when other parts (m) are superposed on these interconnectingly upright parts (m) inside the orderly feed track 11, they are shaked off to the inside of a pocket 12 or directly in the inner part of the pole 2 due to vibration or centrifugal force.
